Answer:
All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:
given the second expression:
x - y = 1
We'll replace y with it's value in the first expression:
x - (y) = 1
x - (5 - 2x) = 1
Now we can expand the resulting equation:
x - 5 + 2x = 1
So <em>neither</em> of the answers provided are correct.
You can then solve for x:
x - 5 + 2x = 1
x - 5 + 5 + 2x = 1 + 5
x + 2x = 6
3x = 6
3x/3 = 6/3
x = 2
After that, you can find y by plugging x into either of the two original equations:
y = 5 - 2x
y = 5 - 2(2)
y = 5 - 4
y = 1
I don’t know if you want both but I’m going to give you both.

Answer:
A=20 degrees
D=70 degrees
E=110 degrees
Step-by-step explanation:
A=20 because a right angle always = 90 so 90-70=20
D=70 because I believe that angles C and D make a right angle, and C = 20 degrees, so we now subtract. 90-20=70
E=110 because D and E = a straight line, which is 180, and sense D is 70 degrees, all we need to do is subtract. 180-70 is 110, so our answer is 110
Hoped this helped, and let me know if I messed up somewhere.
